Abstract :- Security is one of the major Concern to achieve the secure communication

Code coning is considered as the challenge to the software quality. To develop a reliable and authenticated software system, it is required to remove the clone based bugs over the software system. There are number of associated approaches but no one is able to provide the reliable solution. In this work, a combined mathematical model is presented to overcome the limitations of existing approaches. The presented model is divided in four main layers. Each layer is represented by a separate mathematical approach. In the later stage, the weighted phenomenon is used to combine all these approaches to obtain the overall code similarity. The work is presented in the form of an automated tool. The obtained results shows the robustness and accurate detection of code cloning for software system.
